Chemoluminescence of a UV-Irradiated Zn2SiO4–Mn Crystal Exposed to Hydrogen Atoms

The effects of the transfer of reaction energy to electrons and the luminescence of trapped electrons under the influence of the recombination reaction of H atoms on the surfaces of light-sum accumulating Zn 2 SiO 4 –Mn crystals are studied. It is established that the intensity of heterogeneous chemoluminescence (HCL) from preliminarily UV-irradiated samples is directly proportional to the accumulated light sum and governed by trapped electrons, which are responsible for the accommodation of reaction energy through the electron channel with the resulting nonadiabatic chemoelectron excitation and luminescence of a crystal.
